NCD57253GEVB
INTRODUCTION
The NCD57253 Evaluation driver board is designed for evaluation
of the NCD57253.
The NCD57253 is a high current two channel gate driver. It can
directly drive two independent MOFETs in any configuration.
The driver provides 5 kVrms internal galvanic isolation from input
to each output and functional isolation between the two output
channels. The device accepts 3.3 V to 20 V bias voltage and signal
levels on the input side and up to 32 V bias voltage on the output side.
The device accepts complementary inputs and offers separate pins for
Disable and Dead Time control for system design convenience.
NCD57253 is available in wide body SOIC
−
16 package.
DESCRIPTION
The board was created for the ability to verify and test the datasheet
parameters. The board can be externally connected to a power device
to verify real parameters in the system. It contains all the necessary
peripheral components for direct connection to the power devices. The
input bias is configured so the VDDA and VDDB can be powered by
using many types of integrated dc
−
dc power supplies or can be
powered directly from external power source. The PCB design is
optimized to reduce loop areas and provide clear and simple
measurement of all signals. All the parts (except optional dc
−
dc
sources) are TOP mounted which allows easy replacement and can
serve as an ideal reference design for future use.
